Here is a reminder about how the TheFUSIONCUP Knock-out/Play-offs will work:

This is the rule: Playoffs

b) Group assignment will be done using similar format as Nation's Cup rule 13.5 and/or adapted adequately to the number of teams registered.

What does rule 13.5 say ?

11-16: Round robin, 2 groups, with QF, SF and F. #1s choose opponent of other group in QF; cannot meet other #1 in SF, cannot meet best classified of own group in SF.
11: (1,4,5,8,9) and (2,3,6,7,10,11), 9 weeks
12: (1,4,5,8,9,12) and (2,3,6,7,10,11), 9 weeks

Point being: After the places are decided, the teams finishing #1 in Orion and Andromeda will choose their opponent. After those choices, then the highest finishing teams not chosen, goes into the slot away from the #1 team's side of the play-off bracket.
